Leak Sealing

Water leakage often occurs through concrete cracks, concrete construction joints, masonry cracks and blockwork. The TamPur polyurethane injection resins have been designed specifically for such applications and range from low viscosity rapid reacting rigid leak sealing resins for high water cut off and void filling to flexible and semi-flexible polyurethane leak sealing resins for general water stopping repairs. Many of our polyurethane resins are used extensively for tunnel waterproofing, shaft waterproofing and basement waterproofing where leaking joints and leaking cracks occur.

The TamAcryl range of acrylic leak sealing resins offer a ultra low viscosity injection resin for hairline concrete cracks and joints, masonry cracks to sealing honeycombed locations in concrete retaining walls and slabs to brick work waterproofing. TamAcryl 2000 incorporates an anti-corrosive agent that actively protects the steel reinforcement from corrosion and holds a WRAS Certificate.

Tunnelling and mining


A basic introduction to our technology…

Our Waterproofing products include:

  • Powder additives for waterproofing concrete
  • Brush and spray applied cement based waterproof membrane systems for waterproofing walls and foundations
  • Liquid applied solutions for waterproofing concrete slabs and decks.

The TamSeal 5, TamSeal 10 and TamSeal 10F cement based waterproof coatings have been designed for ease of application to a variety of building substrates. These polymer enhanced cement based materials offer a range of elongation and water pressure resistance depending on the system chosen and can be applied as a damp proof membrane to ground slabs, as a waterproof tanking material to water tanks, cellars/basements, swimming pools to below ground waterproof coatings for retaining walls and slabs.

Our TamSeal Admix, TamSeal 20, TamSil 1 and TamSil 7 waterproofing materials are based on modified silicate technology designed for ease of application for a variety of concrete waterproofing requirements.

TamSeal Admix is an integral concrete waterproofing admixture capable of withstanding high hydrostatic water pressure and can be used for basement waterproofing, waterproofing water retaining structures, waterproofing concrete slabs and decks.

TamSeal 20 is economic cement based waterproof membrane applied to new or existing concrete structures. The active chemicals readily track into the concrete capillaries forming a barrier to water ingress.

TamSil 1 and TamSil 7 are liquid waterproofers that can be simply sprayed or brush applied onto the concrete surface where they actively react in the concrete capillaries to form an integral waterproof barrier.

TamCrete Plug offers a fast and effective material for plugging active leaks in concrete substrates.

Ground Stabilisation

Tam International manufacture a range of soil stabilisation and soil improvement products ranging from acrylic, polyurethane and colloidal silicate injection resins to micro fine cement grouts.

Our ultra low viscosity acrylic and colloidal silicate injection resins are used to improve ground stability through consolidating the soil and forming impermeable barriers through permeation grouting techniques.

Our range of polyurethane ground stabilisation resins are used extensively for underpinning, permeation grouting and generally improving ground bearing capability. These resin materials are also used for creating sub grade grout barriers through permeation grouting and forming ground piles where sheet piling is impractical.

Many of our injection resin and grout materials hold WRAS Certification making them ideal as a soil stabiliser adjacent to water ways and other sensitive locations.

In addition to soil improvement, underpinning and permeation grouting, Tam products are used for fissure grouting in rock, injection ahead of TBM’s to void filling behind tunnel linings and shafts.
