Combination Drains in Austin & San Antonio
Our Combination Drains Services
Some properties have both surface runoff and wet ground. A coordinated system may use different collection methods for different parts of the site.
Separate the Water Sources
Different sources of excess water are evaluated individually to determine how each area should be addressed within the overall drainage plan.
Coordinate the Drainage Routes
Surface and subsurface components are planned together, with collection routes and discharge points coordinated so the system works as intended.
Coordinate the Surrounding Work
Excavation, landscaping restoration, and related concrete work are planned around the drainage installation to avoid disturbing the same areas unnecessarily.

More Ways to Manage Water Around Your Property
Surface Drains
Surface inlets and channels collect water from low areas or hard surfaces. Their placement should follow the way water moves across the property.

A French drain uses a subsurface collection route. Its location, surrounding material, and outlet matter as much as the pipe.

Pumping may be considered when a suitable gravity route is unavailable. Collection, power, discharge, and maintenance must be planned together.
Read MoreFrequently Asked Questions
Discuss these points alongside the proposed combination drains. Keep the scope, exclusions, and next steps in writing.
What affects the cost?
Foundation type, the extent of the work, access, and related drainage or concrete tasks affect the scope. Compare written proposals that explain what is included and excluded.
How long will the work take?
The schedule depends on the evaluated scope, site conditions, and weather. Ask about access restrictions, curing where relevant, and how any changes will be communicated.
What happens to landscaping?
Work routes and excavation may affect planting and paving. Agree what can be protected, what will be disturbed, and which restoration tasks are included.
Can the work be done in stages?
Some work can be sequenced, but the suitability depends on how the parts of the property interact. Ask which tasks should happen together and what deferring work could change.
What records should I keep?
Keep the agreed scope, any reports, payment records, completion documents, and applicable warranty terms with the property records.
