Below Grade Vault Chemical Injection

A below grade vault had major water intrusion causing high levels of deterioration. There were approximately 6” – 8” of standing water with the main source being pipe sleeve penetrations.

STRUCTURAL was hired to perform the repairs. Bringing on their engineering and design partner, STRUCTURAL TECHNOLOGIES, the team proposed a leakage mitigation plan.

6” – 8” of standing water in electrical basement causing deterioration

Main source of water ingress was through pipe sleeve penetrations

STRUCTURAL TECHNOLOGIES proposed a leakage mitigation plan

Grout injection at all problematic pipe sleeves

Installed concrete curb, sump pump to create perimeter trench

Completed repairs prevented water leakage

Project Overview

6” – 8” standing water in basement causing deterioration
STRUCTURAL TECHNOLOGIES helped design a leakage mitigation plant
Grout injection implemented in pipe sleeves
Perimeter curbing and sumps for water control

A below grade vault had major water intrusion causing high levels of deterioration. There were approximately 6” – 8” of standing water with the main source being pipe sleeve penetrations.

STRUCTURAL was hired to perform the repairs. Bringing on their engineering and design partner, STRUCTURAL TECHNOLOGIES, the team proposed a leakage mitigation plan. STRUCTURAL performed grout injection at all problematic pipe sleeves to prevent future leaking. The team also installed a concrete curb and a sump pump to create a perimeter trench.

The repairs significantly reduced the water intrusion and created an adequate control system.
