Site Prep & Earthworks across Metro Vancouver and Fraser Valley

Drainage & Site Prep

Seven Stones prepares sites so water, base depth, compaction, and finished surfaces work together.

Canadian locally owned and operated in BC. Work is provided by Seven Stones Construction Ltd.

Document the site before discussing a scope

Useful drainage and site-prep context starts with observable conditions: high and low points, downspouts, drains, outlets, edges, walls, slopes, surface transitions, and the route water appears to take during rain. Wide photographs and a simple sketch provide more context than a close-up of one low point.

Questions that may need appropriate review

What is visible, and what is only assumed?
Where can the work area be reached, and what limits access or material movement?
Which existing surfaces or structures meet the area being discussed?
Does a municipal, engineering, utility, or other specialist question need to be resolved first?

This content supports a planning conversation. It is not a diagnosis, drainage design, engineering opinion, permit determination, or outcome guarantee.

Audience context

Describe water and ground context in plain language

Home and site planners

Note where water is seen, what changes after rain, which surfaces meet, and whether the area is flat, sloped, or constrained by access.

Property teams

Include nearby walkways, parking, walls, entrances, drainage features, and any shared-access concerns that could shape the conversation.

Useful reading

Use the grading and drainage guide, then compare grading & earthworks or excavation.
