Frequently asked questions
What are the typical soil conditions in Burnaby for residential foundations?
Residential sites in Burnaby often encounter glacial till at shallow depths, providing good bearing capacity, but may also have soft glaciomarine clays or organic layers in low-lying areas. We recommend site-specific subsurface investigations to assess soil strength, groundwater levels, and potential for settlement. Foundation types range from conventional spread footings on till to deep foundations or ground improvement in softer soils.
How does the high water table in Burnaby affect basement construction?
The shallow groundwater table, often 2-4 meters deep, requires careful drainage and waterproofing design for basements. We typically recommend perimeter drains, sump pumps, and water-resistant membranes. For deeper excavations, dewatering systems may be needed, and we assess potential impacts on adjacent structures. Our geotechnical drainage design ensures compliance with local bylaws and long-term performance.
What seismic design considerations apply to Burnaby projects?
Burnaby is in a high seismic zone due to the Cascadia subduction zone. The NBCC 2020 requires site-specific seismic hazard analysis, including soil amplification and liquefaction potential. We perform cone penetration testing (CPT) and vs30/" data-interlink="1">shear wave velocity measurements to classify site class and recommend appropriate foundation and structural designs to mitigate seismic risks.
Do I need a geotechnical report for a small renovation or addition in Burnaby?
Yes, the BC Building Code typically requires a geotechnical report for any addition or renovation involving new foundations, especially in areas with variable soils or high water tables. Our reports provide foundation recommendations, soil bearing capacities, and construction guidelines to ensure safety and compliance. We also assist with permit applications and coordination with municipal engineers.
