Waterproofing is the process of making an object or structure waterproof or water-resistant, so that it remains relatively unaffected by water or resisting the ingress of water under specified conditions. Waterproofing elements include above/below grade, windows, joints, and flashings.

The obvious difference between the two injection systems is that epoxy will restore the structural integrity of the crack or defect in the concrete by filling the crack with a high-strength adhesive that essentially ‘welds’ the cracked wall back together.

Filling the crack or joint with these high-strength epoxies eliminates the movement that would otherwise occur due to temperature swings and wet/dry seasonal cycles.


Polyurethane foam also fills the crack or joint with a resin that expands in the presence of moisture. Unlike epoxy, polyurethane foam is flexible enough to accommodate movement in the crack or joint due to changing soil pressures or minor settlement.

Since polyurethane resin systems expand during the injection, less resin is required to accomplish the repair and can be much more economical to install—especially in wide cracks and loose soil conditions.


Wet Glazing is the installation of glass using elastomeric sealants and butyl tapes to bed the glass and seal it at either face to the framing. Silicone and MS sealants are the most commonly used but polyurethane and polysulphide sealants are also used.

Waterproofing windows

One Part Polyurethane Sealant

  • One part moisturecuring, gun-grade polyurethane sealant. Durable, flexible, and offers excellent performance in moving joints.  It does not require a primer on most construction materials. 

  • Designed for use in precast, masonry, window frame perimeters and similar types of construction joints.

Two Part Polyurethane Sealant

  • Multi-component urethane sealants for sealing and protecting moving joints of all types.

  • Used for perimeter sealing of windows, doors, skylights, expansion joints, flashing, precast/tilt up, siding sealing waterproofing membrane

  • Excellent flexibility and bonds to most substrates without priming.

Silicone Sealant

  • A powerful, flexible product that can be used in many different applications with a water tight sea

  • Does not yellow or discolo

  • Has a long life spa


  • Used to seal windows and make glass installation easier.

  • There are two types: basic adhesive used to hold glass in place and one that expands where it is applied
