Shoring is a critical structural support system used to stabilize excavation walls and protect surrounding structures during construction. It provides safety, maintains excavation integrity, and allows for uninterrupted below-ground work. At XPS, we apply the most suitable shoring method based on site-specific conditions such as soil type, water table levels, excavation depth, and structural proximity. Our team leverages over two decades of expertise to implement shoring systems that are not only compliant with international safety standards but also tailored for the fast-paced, urban construction environment in Dubai. Below are the primary types of shoring systems we offer:

H-Beam shoring involves installing steel H-beams into the ground using rotary drilling or vibration methods. Once in place, concrete panels or timber lagging are inserted between the beams to retain soil. This system is commonly used for both temporary and permanent earth retention. For temporary works, the beams are typically extracted after casting the retaining wall.
Sheet pile walls use interlocking steel sheets driven into the ground using vibration or pressing techniques. The thickness and length of the sheets are determined based on excavation depth and soil conditions. Suitable for temporary or permanent applications, this method is efficient in sandy or soft soils and can be extracted post-construction when used temporarily.
This system consists of a sequence of closely spaced reinforced concrete piles. The piles are drilled and cast in place, typically leaving a small gap (e.g., 50 mm) between them, making the wall non-water-tight but structurally stable. Contiguous piles are well-suited for dry ground conditions and medium-depth excavations.
Secant pile walls are created by overlapping reinforced concrete piles to form a continuous, water-tight barrier. Primary (soft) piles are drilled first, followed by secondary (hard) piles that intersect them. This system is ideal for deep excavations and areas with high groundwater, providing excellent structural and hydraulic performance.
The capping beam is a reinforced concrete element cast across the top of piles (whether contiguous, secant, or H-beam) to distribute lateral loads and align the tops of the shoring wall. It enhances structural stability and provides a uniform platform for anchoring or further construction, such as basement slabs or vertical columns.
