Setting time determines the product to use:

  • If fast setting (~2 minutes) is required - HYDRO STOP is the answer
  • If a slower setting (~10 minutes) material is required, you should select MIX & FIX

Fast setting HYDROSTOP stops outflowing water from concrete dams or inflowing groundwater. 

HYDROSTOP is a pre-mixed cementations’ grey powder combined with accelerating chemicals to produce an instant setting in +- 2 minutes. It expands on setting, is non-staining, frost and salt resistant.

HYDRO MIX & FIX is a slower setting material and used to repair hairline cracks in concrete walls, floors and swimming pools. The product is also commonly used to fit new gatemotor tracks in cutout paving grooves. Cracks need to be opened to at least 30mm wide in order to ensure a proper bond.

HYDRO MIX & FIX sets in 10minutes and reach full strength in about an hour making it perfect for fitment and sealing of weirs and other plastic pool equipment in concrete.

Non-shrinking, no pre-saturation to substrate is required. Thermal expansion and contraction similar to that of ordinary Portland Cement.

Typical Applications

  • Fit or seal around plastic weirs, inlets and light fittings in swimming pools
  • Stop flowing water through holes in concrete and masonry surfaces
  • Seals around pipes, conduits and ducts
  • Can be placed in sub-zero temperatures such as cold rooms
