Underpinning
Underpinning is used to increase the depth of a foundation by constructing new concrete footings lower then the existing footings. Underpinning involves carefully excavating beneath the foundation walls and pouring new concrete footings at a lower depth. Underpinning allows homeowners to safely lower their basement floors, create more livable space, and prepare the home for legal basement apartments. Underpinning not only reinforces the structure but also adds significant long-term value to the property.

Whether you need a industrial concrete slab, concrete foundation, a basement walkout, or a complete garden suite foundation, our experienced team has you covered. From residential to commercial projects, we handle sidewalks, walkways, driveways, concrete stairs, ramps, and large-scale parking lots with expert craftsmanship and long-lasting results.

Waterproofing
Protecting your home from water damage starts with proper basement waterproofing. Waterproofing is the process of preventing water from entering your basement or foundation through walls, floors, or cracks. Whether caused by heavy rainfall, poor drainage, or aging materials, water intrusion can lead to mold growth, structural damage, and costly repairs. Interior waterproofing systems help manage moisture from inside the basement, while exterior waterproofing solutions stop water before it enters the foundation. From sump pumps and weeping tiles to membrane sealing and drainage upgrades, waterproofing services are essential for keeping your basement dry, safe, and healthy year-round.
excavation & land development
Excavation and land development are the first critical steps in any construction project. Excavation involves safely removing soil, rock, and debris to create a stable base for foundations, utilities, drainage systems, or structural additions. Land development services go further by preparing the entire site through grading, trenching, backfilling, and soil compaction to ensure proper drainage and buildability. Whether you’re building a custom home, garden suite, foundation, or retaining wall, professional excavation ensures your project begins with precision and code-compliant ground preparation. Done right, excavation prevents costly setbacks and lays the groundwork for a successful build.
Family owned and operated business! I used CTA for several underpinning, excavation and waterproofing projects now. There is no job too small or too large for them to deal with. They go that extra mile to ensure things are done right and on time. Genuinely hard working people that are always smiling! I'll continue to use them in the future.
