Foundation installation: a guide for pros

What customers ask, how to win the job, and what to put on your profile.

Offering foundation installation

You prepare sites and build foundations, from excavation and footings through forms, reinforcement, concrete and waterproofing. Customers hire you for a level, well-drained base built to the drawings and the inspection.

What customers ask

Do you pour to the engineer's drawings, and when is the inspection?
What concrete strength and reinforcement are you using?
How do you handle weak, wet or rocky soil?
What waterproofing and drainage are included?
What happens if the weather delays the pour?
What warranty do you provide on the foundation?

How to win the job

On the first call, ask for the plans, the soil report if one exists, the site access and the target start, then say what you need to confirm before you bid
Walk the site with the customer, check the soil and the drainage, and mark the utility lines before you quote the excavation
Put the excavation depth, the footing sizes, the reinforcement and the concrete strength in the proposal, so the customer sees the design being built
Show the waterproofing and drainage system you use, and where the water will go, in the quote
Schedule the inspection stages in the proposal and say which inspection must pass before the next step
Show photos of past footings and forms with the reinforcement in place, so customers see the work that will be hidden

What to put on your profile

Post photos of excavation, forms, reinforcement and pours, labeled with the foundation type
List the foundation types you build, such as slabs, crawl spaces and basements, with the soil types you have worked in
Show your waterproofing and drainage work on finished basements and crawl spaces
State the concrete suppliers and the testing you use, and whether you coordinate an engineer's review

Follow-up that helps the customer

Offer a post-build check of the top of the foundation for level, the anchor bolts and any cracks after the first season
Suggest a grading check so water drains away from the foundation as the soil settles
Mention a waterproofing check for basements after heavy rain, since drainage can change over time

Licenses and permits

Foundation contractors commonly need a general contractor license or registration, and many jurisdictions require a permit and inspections for each stage of concrete work. Check with your state and local licensing agencies and your local building department for your license class, bonding and insurance before you bid.

Questions

What do I do if the soil is weaker than the drawings assumed?

Stop the affected work, document the soil with photos and tests, and ask for the engineer's review. Put the changed scope, the added time and the change in cost in writing before you proceed.

How do I handle a pour that gets rained on before it sets?

Follow the mix and the cure plan for the conditions, and do not add water to the surface or finish it while rain is falling on it, since extra water weakens the top layer. Tell the customer and the inspector if the pour is damaged, and document the repair.
