The Ground Underneath Is What Makes or Breaks a Turf Lawn
Homeowners usually switch to synthetic grass to get away from mowing, watering, and reseeding, only to run into a different set of headaches when the groundwork was skipped: rippling fibers, dips where water sits after a storm, or a walking surface that just feels wrong. None of that traces back to the turf product. It traces back to what is packed down beneath it. Grassroots Lawncare starts every Altadena, CA job with careful excavation and a compacted aggregate sub-base built specifically for drainage and long-term stability.
We slope and grade that sub-base so rainwater is carried away instead of collecting underneath the lawn, since trapped moisture below synthetic grass is what eventually leads to musty odors and a mushy, uneven feel. A properly built foundation lets water pass through and clear out the way the system was designed to work.
Clean Seams and Final Touches
Seams that you can spot with the naked eye are one of the most frequent complaints homeowners have about synthetic lawns, and nine times out of ten it traces back to rushed fieldwork rather than a defect in the roll of turf. Our crews fit each seam tightly and anchor every edge securely, so once infill is worked in, you cannot pick out where one section ends and the next begins.
The final step is working infill deep into the base of the fibers, which helps each blade stand up straight for a fuller, more natural look while also adding weight and structure that keeps the lawn performing under everyday foot traffic instead of matting down quickly.

How We Install Your Artificial Lawn
Clearing and Excavation
We remove the old surface and excavate the area, then lay down a compacted aggregate base built for drainage and long-term stability.
Sloping the Base
The sub-base is sloped and graded so water is carried away rather than sitting underneath the finished lawn.
Laying and Seaming the Turf
Turf panels are rolled out and fitted with tight, precise seams so the finished lawn reads as one continuous surface.
Infill and Final Grooming
Infill is worked deep into the fibers to support each blade and give the finished lawn its natural feel underfoot.
Homeowners in Altadena, CA Share Their Experience
A full year in and our lawn hasn't rippled or shifted at all, which is more than I can say for what a neighbor went through with a different crew.
Once the infill went in you genuinely could not point to where the turf panels were joined together. It looks like one solid piece.
Standing water was my main worry given how much it rains here, but we haven't had a single pooling or odor problem since the crew finished.

Questions We Hear Often
It does, provided the base underneath is graded and built correctly. Water should pass through the turf backing and sub-base instead of collecting on top or underneath it.
Rippling is almost always tied to a weak or uneven base, or turf that wasn't stretched correctly during installation, rather than an issue with the material itself.
With tight seam fitting and the right amount of infill, the seams blend in and are not visible once the installation is complete.
Given a solid base and careful installation, a synthetic lawn can hold up well past the ten-year mark, depending on foot traffic and the grade of material chosen.
