Prevent Cracks and Damage with Expert Floor Joint & Membrane

At Riyadh Key Contracting, we specialize in floor joints & membrane in Riyadh and across KSA, ensuring that your concrete floors remain durable. Even small cracks or gaps can grow into big problems if left unchecked. In fact, an industry survey found that 92% of facility managers identified deteriorated floor joints as their top concrete-floor issue. Properly repairing floor joints and applying a quality floor membrane helps prevent those cracks, making your floor last longer and stay strong. When floors expand or contract (for example, a 100 ft slab can grow over an inch in very hot weather), expansion joints give the concrete room to move. If joints aren’t treated properly, the concrete will crack on its own.

If you notice signs like surface cracks, chips, gaps, or raised edges, it’s best to act quickly. Ignoring these defects is risky: water and chemicals can seep into the slab, undermining the base and causing widespread damage. Open joints can also wear out vehicle wheels and equipment prematurely. In one real example, a warehouse manager reported that poor joints made his floor “the worst” and doubled his forklift wheel costs; another only got repair funding after a heavy load tipped and the driver got hurt because of a rough joint. Proper joint and membrane maintenance protects your floor’s integrity and your team’s safety.

Common Floor Joint and Membrane Problems

Cracks and Spalls: The concrete edges around joints can crack, chip, or break off. This creates pits or “spalled” areas that trap dirt and moisture.
Wide Gaps: Joints can open beyond their original design. Wide, empty joints collect debris and let water or chemicals soak into the concrete.
Raised or Uneven Edges: One side of a joint may lift or settle, creating a bump on the floor. These uneven joints are trip hazards and can cause jolts to forklifts or carts.
Damaged Membrane: The protective floor membrane can wear thin, peel, or crack. A damaged membrane means water or spills reach the concrete. Over time this causes rust in reinforcements and concrete degradation. A quality membrane prevents these issues.
Hygiene Concerns: In clean or food areas, open joints are hard to clean and can harbor bacteria. A smooth, sealed membrane makes sanitation much easier.

Ignoring any of these issues lets problems worsen. Minor cracks today often become major, costly repairs tomorrow. Early action on joint repair saves money and reduces downtime.

Floor Joints Repair in Riyadh

Our floor joints repair in Riyadh service follows a proven step-by-step process to restore your floor’s smoothness, By following this thorough process, our repairs return joints to “like-new” condition and keep them intact under tough conditions.

1. Identify Joint Type

Determine whether each joint is an expansion joint (for movement), a control joint (for curing shrinkage), or a construction joint (between pours). This tells us the right repair method.

2. Clean Thoroughly

Remove all debris, old filler, dust, and loose concrete from the joint. We use wire brushes, vacuums, or pressure water to expose clean concrete.

3. Prepare the Joint

If needed, we route or slightly widen the joint to a uniform shape. For deep joints, we insert a foam backer rod. This backer rod sets the depth and reduces filler volume. Proper joint prep is critical for adhesion.

4. Select and Apply Filler

We choose the right sealant: for static joints we may use rigid epoxy; for moving joints we often use flexible polyurethane or fast-curing polyaspartic. We pour or caulk in the material, filling the joint completely.

5. Level the Surface

After application, we strike off excess with a trowel or putty knife so the sealant is flush with the floor. We shape it to a smooth finish and clean away any overflow.

6. Cure and Inspect

We allow the filler to harden (as per manufacturer guidelines). Once cured, we inspect the joint edges to confirm a tight, smooth seal.

Joints Sealant in Riyadh

Joints sealant in Riyadh, KSA refers to the flexible or rigid compounds used to fill and seal those floor gaps. We use premium sealant products chosen for each situation. We select the sealant type based on the joint’s role. Sealants fill joints and make them watertight. For example:

Epoxy Sealants

These cure into very hard, rock-like fillers. They’re extremely strong under load and ideal for control joints (where the concrete isn’t expected to move much). Epoxy’s rigidity keeps joints solid, but it won’t stretch with large movement.

Polyurethane Sealants

These are much more flexible (10–25% elongation). Polyurethane works well for expansion joints, especially in Riyadh’s heat or on exterior floors. It stays rubbery, accommodating thermal expansion. It’s also UV-resistant and durable in sunlight.

Polyurea/Polyaspartic

These are advanced, fast-curing options. They combine strength with flexibility and can often cure within 1–2 hours. Polyurea fillers are excellent for quick repairs and areas needing chemical resistance.

Floor Membrane Services in Riyadh

A floor membrane is a protective coating applied over the entire floor surface (and sometimes walls). Our floor membrane services in Riyadh and Saudi Arabia involve applying high-performance epoxy or polyurethane coatings in a seamless layer. These liquid-applied membranes form a continuous “skin” over the concrete.

Key Benefits of Joint & Membrane Services

Enhanced Durability: Sealing joints and coating floors greatly extends their life. The floor resists cracking and spalling, standing up to heavy use.
Improved Safety: A perfectly flat, sealed floor has no bumps or edges that could cause trips and falls. Workers and vehicles move smoothly, reducing accidents.
Corrosion Protection: By stopping water and chemicals, our membranes protect metal components (rebar, beams, tank walls) from rust. Concrete stays intact beneath.
Easy Cleaning: The seamless, non-porous finish prevents dirt and spills from penetrating. A coated floor is easy to sweep and sanitize, a big plus in food or medical facilities.
Lower Costs: Fixing joint issues early and applying a durable membrane saves money long-term. Experts note that proactive maintenance is far more cost-effective than costly failures.
Better Hygiene: Open cracks can hide bacteria. Our continuous membranes eliminate crevices, so floors can meet strict health standards.
Long-Term Savings: Overall, fewer repairs are needed later. A strong, well-sealed floor means less downtime, less replacement, and more years of service from the slab.
