Kept dry since 1987.

Waterproofing, joints and flooring for the contractors who build Malaysia's landmarks. Applied by our own crews.

0 years on site. CIDB G7, no tender limit. 0 people, all ours.

HYDROCON ENTERPRISE SDN BHD, incorporated 15 June 1987. Registered Grade G7 in building, civil engineering and mechanical works, including B08 waterproofing. Thirty-two staff and seventy-six site workers on our own payroll, so the crew that quotes is the crew that turns up.

Roofs you already know

312 references since 1985, from Merdeka 118 to the hospital on site this year. See the projects

Water finds the weak point.

A cold joint, a corner, an upstand, a pipe. Or a crack in a slab that ponds after every storm. Those are the details we draw, build and check.

When the work is done we flood the area and look for leaks before anyone else does.

The system, layer by layer.

Clients ask what actually goes on the slab. This is our RC roof system as we install it, in the order we install it.

  1. Reinforced concrete slabCleaned, dried and checked for falls.
  2. Base screed to fallCement and sand 1:4, 25 mm average, laid to drain.
  3. PRIMER W, then CHEMFLEX R-100Three coats of reinforced synthetic rubber membrane, fully bonded.
  4. HYDROFOAM HD insulation50 mm extruded polystyrene board over the membrane.
  5. Polythene sheet500-gauge, between the insulation and the protection concrete.
  6. G25 protection concrete75 mm with BRC A5 mesh, saw-cut into 2 m panels, every cut sealed.
  7. DURACOTE HBTwo coats of polyurethane where the roof stays exposed.
  8. Then we pond test.The roof is flooded and checked before handover.

Systems by building zone

Every zone gets its own build-up, drawn layer by layer on the Systems page.

Our crews work across the Klang Valley, Putrajaya, Johor and Penang, and the register runs to Bintulu and Langkawi. Where a specification calls for another manufacturer's system, we apply that.

On site

The work, as it happens.

Roofs, joints and wet areas, by our own crews.

Then we concrete over it.

Power-floated level, then cut into panels, so the concrete cracks at a joint and not across the slab.

The waterproofing system underneath never sees the sun again.
