Temporary drainage during construction

Temporary drainage diverts surface water and keeps excavations dry during the build. We install temporary runs, sumps and pumps as part of enabling works. We maintain them until permanent drainage is in place or the site is handed over.

Temporary drainage during construction usually becomes urgent when recurring symptoms begin affecting programme confidence, compliance, or delivery reliability.

When you might need this

Teams usually investigate temporary drainage during construction when early warning signs start affecting reliability, compliance, or project timelines. This is often the point where decision makers move from observation into scoped technical action.

Common warning signs

The symptoms below are the most common triggers we see before diagnosis and repair planning.

• Site needs to stay dry during build
• Temporary runs and sumps
• Pumping if needed
• Part of enabling works
• Remove or hand over at end

What to expect from the work

We plan temporary drainage from the site layout. We install and maintain it during the works.

How this gets resolved

We deliver temporary drainage so construction can proceed. We remove or hand over as agreed.

Cost and complexity factors

Cost and complexity usually depend on access constraints, total scope, existing condition, and whether related works need to be coordinated in the same programme window.

How we work through the job

We keep delivery structured so scope, sequencing, and sign-off remain clear.

1. Step 1: Initial assessment

   What this step delivers: Root cause and scope are confirmed.

2. Step 2: Method planning

   What this step delivers: Practical repair strategy is agreed.

3. Step 3: Delivery and verification

   What this step delivers: Work is completed and validated.
