Flooring Systems

The Problem

Water infiltration through substrate concrete where damp proof membrane has failed. Greater use is being made of below ground structures requiring effective waterproofing.

The Solution

Active water infiltration must first be arrested using Fastfill WP, a rapid setting, Portland cement based mortar which sets in 2 minutes. This non-caustic mortar is more reliable and safer to use than traditional cement admixtures.

The surface is then saturated before priming with Cemprotec EF Primer, to seal the concrete prior to the application of a 2mm coat of Cemprotec E-Floor. This high performance cement and epoxy modified polymer coating is capable of withstanding 10 bar hydrostatic pressure yet is tough and durable enough to withstand heavy trafficking.

The Problem

Treatment of damp or freshly laid concrete floors without the risk of osmotic blistering when impervious finishes are subsequently applied.

The Solution

Cemprotec E-Floor is applied to prepared and saturated concrete floors that have been primed with Cemprotec EF Primer. It is poured out and spread to a minimum 2mm thickness prior to de-airentraining with a spiked roller.

To aid curing and enhance the adhesion of any coatings that may be subsequently applied, a fine quartz sand can be broadcast into the surface of the freshly laid material. Only 48 hours curing is required before impervious floor coatings and finishes can be laid, which will be resistant to subsequent osmotic blistering. Please consult our technical department regarding compatibility tests.

The Problem

Deterioration of the surface of concrete slabs and reduction in slip resistance through freeze-thaw and trafficking exposure.

The Solution

All potholes and damaged areas are first reinstated with Fastfill, a shrinkage compensated, fibre reinforced, Portland cement based mortar, which sets in 10 minutes.

Following saturation of the substrate and priming with Cemprotec EF Primer, the mixed Cemprotec E-Floor HB is poured out and spread to a minimum depth of 3-6mm using a skid leveller, prior to spike rollering to remove entrapped air. Whilst the surface is still wet a dried, quartz sand is broadcast into the surface to provide a slip resistant finish and to aid curing. Excess sand can be removed after a minimum cure time of 4 hours. To enhance longevity the surface can then be sealed with Cemprotec Sandseal 75.

The Problem

Demarcation of special needs parking spaces or on trafficked areas.

The Solution

Coloured quartz sand can be broadcast into freshly laid Cemprotec E-Floor or E-Floor HB not only to act as a curing aid but also to introduce a delineation or a decorative effect into the system.

After a minimum of 4 hours curing, the excess sand is removed and the surface sealed with Cemprotec Sandseal 75, a clear, non-yellowing, high performance moisture triggered coating is applied by squeegee or roller. This hard wearing coating exhibits excellent chemical resistance and increase the durability of the slip resistant finish.

The Problem

Reinstating joint nosings on floors slabs or treads on stairs.

The Solution

Following breaking out of unsound concrete and thorough saturation of the substrate, joint nosings on floor slabs or treads on stairs can be reinstated with Fastfill. This shrinkage compensated, Portland cement based mortar, which benefits from polymer and fibre modification, sets within 10 minutes to give a durable reliable repair even in the most heavily trafficked areas.

When carrying out deeper repairs, the product can be bulked out with either a coarse aggregate or a sharp concreting sand to provide a cost effective solution.

The Problem

Repairing voids or worn trafficked surfaces or runways where rapid return to service is required.

The Solution

All areas should be thoroughly prepared to remove contamination and unsound concrete and the edges of the repair stepped to a minimum depth of 10mm to prevent feather edging. Ensure that the substrate is saturated without any standing water.

Where speed of reinstatement is important, all voids and removed concrete should be reinstated with Fastfill, a shrinkage compensated, polymer modified, Portland cement based repair mortar, which sets in 10 minutes.

In areas where speed is not critical, Monomix HD, a single component, high strength, polymer modified fibre reinforced mortar, provides a durable solution.

The Problem

Levelling out of rough, tamped concrete prior to the application of a flooring system.

The Solution

If concrete floors have extremely uneven surfaces, it is important to level them out prior to the installation of a flooring system. Cemprotec Levelling Coat is ideal for use as a flowing screed prior to the application of Cemprotec E-Floor or Cemprotec E-Floor HB in applications where the concrete substrate is particularly uneven.

Cemprotec Levelling Coat is always used as a base layer for another floor protection product over the top. It is ultimately designed for use with Cemprotec E-Floor (where a 2-3mm thick flooring system is required) or Cemprotec E-Floor HB (where a 3-6mm finished application is desired) but it can also be used in conjunction with alternative flooring systems such as polyurethanes, epoxy-based systems, polyureas and methyl methacrylate.

The Problem

Concrete repair and protection of a previously coated balcony area where crazing is evident in the paint or coating.

The Solution

All loose material should be removed before areas requiring concrete repair are treated with Steel Reinforcement Protector 841 and Monomix repair mortar.

Monolevel 250F fine grade cementitious fairing coat should then be used to level out the surface of the balcony area and provide an even surface before re-coating can be carried out.

Monolevel 250F can be applied up to 4mm in a single layer and can be feather edged. Bond-Prime should be used to seal the substrate before the application of one or a combination of Flex-crete’s Monodex protective coatings.

This repair and protection system will transform the appearance of balconies, providing excellent waterproof and anti-carbonation protection for up to 15 years.
