Waterproofing & Concrete Protection
Waterproofing and concrete protection products for every stage of a concrete project, supplied from stock across Africa. They include SABS-marked damp proof membranes (DPM) and construction plastics in 250, 375 and 500 micron, orange tank membrane for basements, damp proof course (DPC), GCCM concrete mats for canals and slopes, CPL concrete protection liners for sewers and tanks, and CureLock hessian for curing fresh concrete. One supplier, from the slab to the channel lining, with installation available.
| About Waterproofing & Concrete Protection
Concrete only performs as well as the protection around it. Moisture rising from the ground, water pressure against basement walls, erosion in open channels, chemical attack in sewers and poor curing in the first days after a pour all shorten the life of a structure. This category brings together the products that prevent each of these problems, so contractors, engineers and developers can source everything for a concrete job from one supplier.
For damp proofing and waterproofing in buildings, we supply SABS-marked construction plastics to SANS 952. Our 250 micron black underlay and green under-surface membrane are laid under floor slabs, 375 and 500 micron orange tank membrane protects basements and retaining walls, and polyethylene damp proof course (DPC) stops rising damp in brick and block walls. Across Africa these are known as DPM, construction plastic, builders plastic, 1000 gauge polythene or DPM nylon, and we stock every common grade, including jumbo rolls for large slabs.
TILTEX is a needle-punched composite of a cement-sand mixture between polypropylene nonwoven geotextiles. The manufacturer lists cement-mixture weights of 7, 9, 10 and 12 kg/m². TILTEX Plus incorporates an additional polyethylene geomembrane for waterproofing. For concrete protection in civil works, TILTEX GCCM concrete mats line canals, ditches and slopes without formwork or batching plants. CPL concrete protection liners shield sewers, manholes and tanks from corrosion, and CureLock jute hessian keeps fresh concrete wet while it cures, so it reaches full strength without shrinkage cracks. Together they cover every stage of a concrete structure, from the slab on the ground to the lined channel.
Every product is supplied from stock with delivery to more than 30 countries across Africa, backed by mill certificates and compliance documentation. Our certified crews can also install GCCM, CPL liners and curing systems on site, with full QA/QC records handed over at completion. Send your BOQ or drawings, and our team will match the right product and grade to your specification.

| Types of Waterproofing & Concrete Protection
Damp Proof Membrane (DPM)
SABS-marked black and green polyethylene sheeting to SANS 952, in 250 and 500 micron, laid under slabs and foundations to stop rising damp.
Orange Tank Membrane
375 and 500 micron SANS 952 Type A sheeting for waterproofing basements, retaining walls and other below-ground structures.
GCCM Concrete Mats (TILTEX)
Cement-filled geotextile that sets hard after wetting, for lining canals, ditches and slopes without formwork or batching plants.
CPL Concrete Protection Liners
HDPE liners with cast-in anchor knobs that lock into the concrete, protecting sewers, manholes and tanks from chemical attack.
Concrete Curing Hessian (CureLock)
Jute hessian in 213 and 270 g/m² that keeps fresh concrete wet while it cures, for full strength and fewer cracks.
| Benefits of using Waterproofing & Concrete Protection
One Supplier, Every Stage
From the membrane under the slab to the lining of the channel and the curing of the pour, you can source everything for a concrete project in one order.
Certified Products
Each range meets its own recognised standard: SANS 952 for DPM, CE marking for GCCM, ASTM testing for CPL and IS 2818 for hessian. Certificates are supplied with every order.
Longer-Lasting Concrete
Protecting concrete from moisture, erosion, chemical attack and poor curing prevents the failures that cause most early repairs.
Supply or Install
Buy materials only, or use our certified crews for GCCM, CPL and curing, with full QA/QC records handed over at completion.
Delivered Across Africa
Stock is held for fast dispatch to more than 30 countries, including jumbo rolls and bulk quantities for large projects.

| Specifications for Installing Waterproofing & Concrete Protection
DPM: Lay on a compacted sub-base blinded with at least 50 mm of well-tamped sand, free of sharp stones. Use the widest rolls practical, lap joints by 100–150 mm and seal them, turn the sheet up at the walls, and patch any tears before the concrete is poured
Tank Membrane: Apply to the outer face of basement and retaining walls, sandwiched between structural elements so it is fully supported against water pressure. Lap and seal all joints to the manufacturer's instructions, and protect the membrane from damage during backfilling.
GCCM: Lay the dry rolls on a smooth, compacted and trimmed subgrade, overlap and fix the joints to the TILTEX installation guide, and anchor the edges in trenches. Hydrate with fresh or salt water until fully saturated. The mat sets within hours and needs no formwork or batching plant.
CPL: Fix the anchor knob sheets to the formwork with the anchors facing the concrete, then pour and vibrate so the anchors embed fully. After the formwork is stripped, weld all joints with HDPE extrusion rod and spark-test every seam for a continuous, watertight lining.
Curing Hessian: Place pre-soaked hessian as soon as the concrete can take it without marking, with 150 mm overlaps and all edges covered. Keep it continuously wet for at least 7 days, or longer if the project specification requires, and never let it dry out in between.
QA/QC: Every installation is recorded with material certificates, daily inspection logs, test results and photographs, handed over as a signed record pack at completion.
