Cast-in-Place Wall

The cast-in-place excavated and poured wall, or continuous wall, consists of constructing, underground, a vertical reinforced concrete wall with variable thickness (between 55 and 120 cm), capable of absorbing axial loads, horizontal thrusts, and bending moments, reaching depths of over 50,0 meters. They are generally excavated under polymers, bentonite muds, or in dry conditions. They are usually used for constructing building basements.

Once the cast-in-place wall construction is completed, excavation proceeds as planned, ensuring, as excavation progresses, with temporary or permanent post-tensioned anchors. Its construction is very similar to oblong piles, as it is carried out with the same equipment, but in this case, it is done continuously using tongue-and-groove joints or “water stops” to improve the waterproofing of the panels. In certain instances, cast-in-place walls can serve a different function than containment, such as with waterproofing walls, in which case plastic walls formed by mixes of bentonite-cement are used, or in cases of constructing load-bearing elements using screen groups.
