Deck Waterproofing in Commerce
Long-lasting waterproof coating systems that keep walking decks, roof decks, and balconies protected from water intrusion.
Deck Waterproofing detailsA city that incorporated to keep its industrial land, so most of the work here is commercial.
Takes about 30 seconds. No obligation, no pressure.
Commerce incorporated in 1960 specifically to stop neighboring cities such as Vernon and Los Angeles from annexing its industrial land for tax revenue, and the city still reflects that. There are only about 3,524 housing units in the whole place, roughly 539 per square mile. Waterproofing here leans commercial.
That means roof decks over occupied space, elevated walkways between buildings, mezzanine landings, steel stairs used hard by people carrying things, and loading areas that pond. Different loads, different traffic, different consequences when a surface fails.
The Los Angeles River forms part of the southwestern boundary and the Rio Hondo separates the city from Downey. Flat ground is unforgiving of a surface that does not drain, because standing water has nowhere to go except through whatever it is sitting on.
On an industrial building a leak rarely announces itself as a stain. It shows as rust bleeding from a deck edge, efflorescence on the underside of a slab, or a mezzanine landing gone soft where nobody walks. By the time product gets wet, water has been tracking through the structure a long time.
Facilities cannot simply stop, so we sequence around operations: sections at a time, work windows agreed in advance, no dock left unusable overnight if the building runs on it. We fabricate the steel as well, so a corroded stringer or failed landing gets replaced rather than repaired twice.

A local crew looks at the actual deck, and the quote comes back itemized.
Yes. We section the work and agree the windows in advance so docks, stairs and walkways the building depends on stay usable. On an occupied industrial property that planning matters more than crew size.
It is. The city incorporated in 1960 to keep its industrial land, and there are only around 3,524 housing units citywide. Most of what we do here is roof decks, walkways, mezzanines and stairs.
Not by itself. This is flat river plain ground, so if the slab has no fall the water sits on the new coating instead of the old one. We correct the drainage path first, then waterproof.
