Rammed earth
The rammed earth page →Is rammed earth waterproof? How earth walls handle water
Earth walls are water-resistant rather than waterproof. What that means in practice, how rain, humidity and ground salts actually act on a compacted wall, and the details that keep water where it belongs. Read →Rammed earth advantages and disadvantages: an honest list
What compacted earth walls do genuinely well, where they are the wrong instrument, and the trade-offs worth knowing before the material reaches a specification. Read →What drives rammed earth cost in Saudi Arabia
Rammed earth is priced by what it takes to build — formwork, lifts, labour and testing — not by the soil itself. Here is what actually shapes a rammed earth budget in Saudi Arabia, and when a plaster finish is the smarter route. Read →How long do rammed earth walls last?
Earth walls have stood for centuries, and the material itself does not really wear out. What decides the lifespan of a rammed earth wall is water — where it lands, where it sits and where it leaves — and that is a detailing question, not a materials one. Read →Does rammed earth work in a hot climate?
Dry heat is an advantage for a material that gains strength by drying, and a discipline for everything else. What actually changes on a Gulf rammed earth site, from mix trials to formwork cycles. Read →Rammed earth feature walls: how to get the strata look inside
Two very different routes lead to the same interior. One is a compacted earth wall built in place; the other is a 7-10 mm clay plaster. Knowing which you are specifying decides your programme, your budget and your structure. Read →Specifying rammed earth in Jeddah: what architects need to know at concept and tender
Rammed earth is moving from mood board to buildable line item on projects across the Kingdom. Here is how to specify it at concept and tender stage so samples, mock-ups, engineering acceptance and procurement all line up. Read →Rammed earth durability in the Gulf climate: how walls age and what maintenance involves
Rammed earth has served hot, arid climates for centuries, and it is well suited to the Gulf — but owners and FM teams deserve straight answers about how it weathers. Here is what to expect, what to plan for, and where a plaster finish is the smarter route. Read →Rammed earth in Riyadh: how in-situ walls are built in Saudi Arabia
Rammed earth has moved from reference image to live specification across the Gulf. Here is how in-situ rammed earth walls are actually built — the formwork, the lifts, the testing — and why the method belongs in Saudi Arabia. Read →Rammed earth structural guide: lifts, formwork and testing to 8 MPa
How an in-situ rammed earth wall is engineered, built and verified — from formwork and lifts to acceptance testing referencing New Zealand's earth building standards, with Al Kaaban Resort in Qatar as the built example. Read →Is rammed earth sustainable? A straight answer on carbon, waste and scorecards
Rammed earth has a strong sustainability case, but it is not automatic. Sourcing, cement content and detailing decide the number, and "contributes to" is the honest verb where WELL, LEED and Mostadam are concerned. Read →Rammed earth thermal performance: thermal mass, time lag and cooling loads
Earth walls are heavy, slow and good at flattening peaks. What that does and does not do for cooling loads in the Gulf, and where insulated double-skin rammed earth comes in. Read →Rammed earth vs concrete: how do they really compare?
Both are monolithic mineral walls cast against formwork. The binder is what separates them — and that single difference drives appearance, thickness, programme, repair and carbon. A straight comparison for architects and contractors in Saudi Arabia. Read →Rammed earth vs rammed earth plaster: when to build the wall and when to specify the finish
A structural rammed earth wall and the Clayworks Rammed Earth Finish share the same layered strata, but they sit at opposite ends of cost, programme and engineering. Here is how we help Saudi Arabia teams decide between them. Read →How thick should a rammed earth wall be?
Wall thickness is not a style decision. It falls out of the load path, the thermal performance you are chasing, the formwork you can practically build and the openings you want to cut. Here is how those four resolve. Read →Stabilised vs unstabilised rammed earth: what is the difference?
Almost every contemporary rammed earth facade you see is stabilised. Here is what stabilisation does to the wall, what you give up in return, and when an unstabilised mix is still the right call. Read →UAE Pavilion at Expo 2023 Doha: rammed earth at civic scale
Our own crews built the UAE Pavilion at Expo 2023 Doha as a complete pavilion in in-situ rammed earth, and the project took the Gold Award for Best Self-Built Pavilion. Here is what it demonstrates about earth construction at civic scale in the Gulf. Read →What is rammed earth?
A wall made by compacting damp earth in layers between formwork. No render, no paint, no cladding — the material is the finish. Here is how it is made, what goes into it, and where it is being built in Saudi Arabia and the wider Gulf. Read →Clay plaster
The clay plaster page →Can clay plaster be used in bathrooms and kitchens?
Clay plaster is welcome in bathrooms and kitchens right up to the point where water hits the wall. Here is where that line falls, and what to specify beyond it. Read →How do you clean and repair clay plaster?
Clay plaster is cleaned dry and repaired in the same material it was made from. Here is the method we hand over with every wall we install, written for owners, hotel housekeeping and facilities teams in Saudi Arabia. Read →Is clay plaster durable? Scratches, knocks and cracking, honestly
Clay plaster is a mineral surface, not a coating. Here is what actually marks it, what makes it crack, and how it ages in real homes and working venues. Read →Does clay plaster regulate humidity?
Clay is hygroscopic, so a clay-plastered room breathes with the air in it. Here is how the mechanism actually works, what it can and cannot do, and how it behaves in a Gulf interior that is air-conditioned most of the year. Read →Clay plaster for Riyadh homes and villas
Clay plaster gives Riyadh interiors a surface that quietly manages moisture and adds nothing to the air. Here is how the Clayworks range works, where it belongs, and the villa that proves it. Read →What can clay plaster be applied to? Substrates, primers and preparation
Clay plaster is a thin finish that inherits everything the wall behind it does. Here is what it can be applied to, what each substrate needs first, and the site conditions that decide whether the finish holds. Read →Clay plaster vs lime plaster: which belongs in which room?
Clay and lime are both mineral plasters, but they set by completely different means — and that single difference decides which rooms each one belongs in. Read →Clay plaster vs paint and gypsum: how do they really compare?
One is a film of colour on a board. The other is the surface itself. A plain comparison of depth of colour, texture, air quality and lifecycle, including the cases where paint is still the right specification. Read →Clayworks in Saudi Arabia: sole distributor and approved applicator for the Middle East
Conmarble is Clayworks' sole authorised distributor and approved applicator across the Middle East — which means the clay plaster on your drawings and the artisans who apply it come from one company, under one contract. Read →What is clay plaster, and why do designers specify it?
Clay, graded sand and mineral pigment, applied by hand. A short guide to what clay plaster actually is, the finishes it comes in, the places it must not go, and the reasons it keeps appearing on Saudi finishes schedules. Read →Lime plaster & tadelakt
The lime plaster & tadelakt page →Is tadelakt waterproof? What burnishing and soap really do
Tadelakt sheds water rather than blocking it. Understanding that difference is what keeps a tadelakt shower looking right in year five. Read →How long does lime plaster take to cure?
Lime plaster sets in hours and carbonates for months. Knowing the difference is what keeps a programme honest, and what stops a good finish being spoiled in week two. Read →Does lime plaster resist mould? The chemistry, and where it actually helps
Lime's resistance to mould is chemistry rather than marketing. But the chemistry only does part of the job, and the rest is decided long before the plasterer arrives. Read →Lime plaster and tadelakt in Saudi Arabia: wet-area finishes done properly
Tile is not the only answer for a bathroom. Lime plaster and tadelakt give wet areas across Saudi Arabia a seamless, grout-free surface that has handled water for centuries — provided the right material goes in the right zone. Read →Lime plaster vs cement render: which one should you specify?
Two mineral coatings, two entirely different chemistries. One dries the wall out, moves with it and can be patched. The other is harder, stiffer and far less forgiving of a mistake made behind it. Read →Polished plaster vs tadelakt vs microcement: what is the actual difference?
Three smooth, seamless finishes that get specified interchangeably and should not be: what each one is made of, where it performs, and how to pick between them on a Saudi project. Read →Tadelakt maintenance: how to clean and care for a burnished lime bathroom
Tadelakt is maintained, not sealed. The routine is short, the list of things that damage it is specific, and both are worth knowing before the first shower is ever run. Read →What is tadelakt? The Moroccan lime plaster, explained
Tadelakt is the lime plaster of Marrakech: compressed with a stone and sealed with olive soap. Here is how it is made, why it sheds water, and where it earns its place in a Saudi Arabia bathroom. Read →Microcement
The microcement page →Does microcement crack?
The most searched question about microcement is also the most misdiagnosed. The material itself is hard, well-bonded and reinforced; the cracks people photograph are almost always the substrate talking. What actually causes cracking, how a correct system prevents it, and what repair honestly involves. Read →Is microcement waterproof?
Cemher describes Microdur Plus as waterproof in mass, and the phrase is worth taking seriously — both for what it promises and for what it does not. Where microcement genuinely works in wet areas, what the sealer actually does, and the one place it must never go. Read →Can microcement be used in bathrooms and showers?
The bathroom is where microcement earns its reputation: one material from floor to ceiling, no grout, no joints, and a data sheet that genuinely permits it. What a correct wet-room build-up contains, where the waterproofing really sits, how the finish lives with Gulf water — and what we learned installing it through the shower rooms of a Doha hotel. Read →Microcement colours and textures: how do you choose well?
The colour is in the material, not on it. How microcement colour is actually made, what grain size and the trowel contribute, how the sealer sets the sheen, and why no tone should be approved anywhere except a sample panel in the real room. Read →Microcement floors: what should a specifier know?
A continuous floor at a few millimetres, hard enough for lobbies and stairs. Which Cemher systems belong on floors, what the substrate must provide, how underfloor heating is handled, and how the material behaves under Riyadh traffic. Read →Is microcement suitable for kitchens and worktops?
Kitchen worktops and counters are on the Microdur Plus data sheet, so the specification is legitimate — and so is the sentence a few lines below it about vinegar. What microcement genuinely offers a kitchen, how it behaves under heat, knives and daily cooking, and the cases where stone or tile remains the honest recommendation. Read →Can microcement be used outdoors?
Exterior use is on the Cemher data sheet, not just in the brochure: walls, ceilings, terraces and outdoor pavements are all listed. The limits are on the same sheet, and in the Gulf they are the part worth reading first. A plain account of where microcement works outside, and the conditions it needs to get there. Read →Can microcement be applied over existing tiles?
Old ceramic tile is a listed substrate on the Cemher data sheet, and the system is applied to it directly, with no bonding bridge. That makes microcement one of the few honest routes to renovating a tiled room without demolition. Here is what the data sheet actually says, and the cases where the tiles still have to come off. Read →Can microcement be used in a swimming pool?
Pools are where microcement specification gets binary. One product in the Cemher range is tested for immersion; the flagship interior product is expressly excluded from it. Which system goes in the water, which serves the deck around it, and what the two Doha pool projects in our portfolio actually used. Read →How thick is microcement, and why does it matter?
The whole system lands at about the thickness of a coin. What actually sits inside those 2 to 3 millimetres, why thinness is the material's advantage rather than its weakness, and the things thickness does not decide — waterproofing above all. Read →Microcement, epoxy or tiles: which belongs in a Gulf wet area?
Wet areas in the Gulf are hard on finishes: hard water, aggressive cleaning regimes, air conditioning cycling against humidity, and handovers that never leave enough time for curing. Tiles, epoxy and microcement all have a legitimate claim to these rooms. The honest answer is that each wins somewhere, and the zone decides. Read →Microcement vs limewash: what is actually being compared?
Both are mineral, both are matt, both photograph beautifully, and the resemblance ends there. One is a coating hard enough to be a floor; the other is a paint whose whole virtue is its softness. Comparing microcement and limewash is less about which is better and more about noticing they were never competing. Read →Microcement walls and ceilings: how does the seamless plane work?
One material from skirting to soffit, without a joint. How microcement behaves on walls and ceilings, the wet-wall capability that separates it from clay, the texture and sheen options, and what the wall underneath has to provide. Read →What is microcement, and where does it belong?
Cement, polymer resins and mineral pigment, trowelled on at a few millimetres and sealed. What microcement actually is, the Cemher systems we install, where it belongs, where it does not, and why it keeps appearing on Saudi finishes schedules. Read →Clay wash & limewash
The clay wash & limewash page →How is clay wash applied?
Two brushed coats over a properly prepared wall — the method is short. What decides the result is everything before the brush: the substrate, its absorbency, and the honesty of the survey. An application guide for specifiers and site teams. Read →Clay wash vs limewash: what is actually different?
Both are breathable mineral paints with centuries behind them, and they are constantly mistaken for one another. The binder is the whole difference — clay that dries against lime that turns back into stone — and it drives everything a specifier cares about. Read →What is a limewash wall finish?
Slaked lime, water and earth pigment, brushed on and left to turn back into limestone. What limewash actually is, where the cloud-like movement comes from, how it behaves inside and out, and how it relates to the lime plaster and tadelakt work we install across Saudi Arabia. Read →What is clay wash, and where does it belong?
Fine clays and mineral pigment, brushed on at paint weight. A plain guide to what clay wash actually is, how it differs from clay plaster, what its breathability and VOC figures really say, and the rooms it belongs in. Read →Resin bound aggregate
The resin bound aggregate page →How long does resin bound aggregate last in Saudi Arabia?
UV, surface heat, blown sand and daily traffic are the four things a resin bound surface has to live with in the Gulf. Three of them are settled at specification stage. One is handled with a brush. Read →Is resin bound aggregate permeable, and how does the water get away?
Permeability is the reason resin bound paving turns up in landscape and public realm specifications. It is also the property most often assumed rather than designed for. Read →Resin bound vs resin bonded: what is the difference?
The two names differ by one letter and the systems differ by nearly everything that matters. One is mixed and trowelled, the other scattered onto adhesive. Here is what that changes on site. Read →What is resin bound aggregate?
A surfacing system rather than a coating: stone fully coated in resin, trowelled out on site, and permeable by design. How it works, and where it belongs on a Gulf project. Read →Still deciding?
Send us the finishes schedule, the drawings, or a photograph of a wall you liked. We will tell you which material actually belongs on it — and what it takes to build.
