BGL has established relationships with suppliers to ensure we are able to specify, supply and install technically appropriate and cost-effective products tailored to site specific applications in a timely manner. Our Solutions typically include
the following products:

Venting
- Provides an important layer of protection by safely managing contaminants of concern
- Takes the form of pressure relief, passive subfloor dispersal, active, and building ventilation
- Is typically supported by a network of intakes, exhausts, and passive or active ventilators

Geocomposites

Venting Media

Inlets / Outlets

Active Ventilators

Membrane
- Membranes provide a barrier against harmful contaminants like soil vapour and landfill gas
- Membranes offered by BGL were selected to comply with industry best practice
- Also act as a damp proofing membrane, protecting properties from moisture ingress
Spray Applied

Hybrid Membrane

Welded Membrane

Waterproofing
- Waterproofing represents less than 1% of the total building cost, however, accounts for 80% of post construction defects
- Waterproofing products prevent infiltration into your basement or structure, protecting it from damage and structural issues caused by water ingress
- BGL offer a range of passive, active, and liquid membranes best suited to your structural situation

Passive

Active

Liquid

Structural Enhancement
- Structural enhancements are used to provide an additional layer of protection to the built form in gas/vapour ingress and waterproofing scenarios

Waterbars

Water Stops

Puddle Flanges

Additives

Voids

Remediation and Retrofitting
- Negative tanking may be required where waterproofing has either been omitted or defective
- Polyurethane crack injection can be a very effective way of reducing or eliminating water ingress pathways into basements
- Retrofit coatings can be applied to existing structures when exposed to ground gases or vapours
- Internal ventilation or purification can support your indoor air quality when dealing with historical problems
- BGL can support source identification to propose effective strategies
