Injection Waterproofing for Arrest of Groundwater Ingress

Building and Structural Maintenance and Remedials

AW Environmental Solutions (AWES) would like to make you aware of their unique

Polymer Resin Injection Waterproofing System

 

The common Groundwater Ingress problems addressed occur either in the construction phase or in the service life of a building or civil engineering structure:

  • Groundwater ingress through secant piled/reinforced concrete basement retaining walls.
  • 'Gushing' high pressure groundwater ingress through failed expansion joints in underground reinforced concrete culverts, access chambers, tunnels and basement car parks.
  • Below ground service duct entries into industrial sub-station buildings when groundwater floods basements entering via the inside of the ducts/tracking the external duct wall or by other means.
  • Trickling groundwater ingress into masonry/reinforced concrete lift pits and basements which exist without traditional tanking membranes, or the waterproofing membrane has failed.

The Injection Waterproofing System remedies all problems associated with rainwater leakage through the exposed top deck of multi-storey car parks and leakage of liquids/potable water from liquid retaining concrete tanks and reservoirs (potable water).

 

Polymer Resin Injection Waterproofing involves:

  • Drilling holes in the concrete/masonry adjacent to the crack-joint defect directed to intercept the crack/joint. 
  • Temporary compression seal steel injection packers are installed to facilitate injection. 
  • Inert, low viscosity, acrylic based hydro-structural resin (with controllable reaction time) is injected via the packers into the structure using a high pressure two-component injection pump.
  • Micro-cracks (0.2mm) are sealed as the low viscosity flexible resin cures

 

AWES Also offer remedial solutions for associated maintenance problems such as:

  • Rising damp in old/historical buildings (injected dpm). 
  • Internal wall coatings (alternative to PVC panels) in internal food production areas where the working environment is damp, humidity is high and condensation is present.

 

AWES would welcome the opportunity to conduct a walkover survey of your site/premises please contact us for details.

As Approved Contractors we provide remedial proposals 'free of charge' with warranties provided on completed works as appropriate.
