Foundations are typically built with masonry, such as concrete block or brick, or with poured concrete. Masonry materials offer high compressive strength and are much more resistant to damage from moisture and soil than wood and metal materials. A masonry foundation typically extends above the ground to protect other building materials from moisture and other damaging effects of ground contact. Masonry foundations usually are reinforced internally with metal rebar or other materials. Contractors will most typically use hydraulic cement to seal around pipes or raceways that penetrate the masonry or concrete foundation.
Some building foundations are built with treated wood posts or piers. In this case, the foundation supports are driven deep into the earth and/or rest on rock or concrete pads. Posts and piers often are used when building on or near water or where the land is prone to flooding.
Essential foundation installation services we provide:
Backfill
A high groundwater table can limit the foundation depth as well as the type of foundation that can be used.
Excavation
Flexible excavation solutions can be provided depending on different construction methods after foundation layout marking.
Footings
Typically, footings are constructed from concrete that has been poured into an excavated trench and reinforced with rebar.
Walls formwork & concrete pour
Wall formwork can be made of wood, steel, aluminum, or other materials. Concrete pouring can include various choice of such as materials, concrete and sand.
Pouring/ Finishing Concrete Floor
Disregarding other factors, the minimum depth of a foundation is typically no less than 18 inches to allow for the removal of topsoil and variations in ground level.
Drainage Pipe
Or Weeping Tile
Weeping tiles and French drains are two different drainage systems. Weeping tiles and French drains both collect water, but their placement and output differ.
Grading or
Physical Site Levelling
Grading or Physical Site Leveling can be done to perfection with Corra’s wide variety of tools and equipment
Waterproofing
Waterproofing materials aren’t made to fill big holes or honeycomb shapes. You’ll need to fill these, preferably with grout that doesn’t shrink or a good patching cement.
