Removing Floor Drain

[fftfk]

All,

I recently built a house with a 3 bay garage. The builder asked if I wanted drains in each bay and I responded yes without putting much thought into it. Each bay has about a 6 foot long trench drain with floors sloping towards the drain. The floor has radiant heat and is epoxy coated.

I like to do projects in the garage (work on my cars, minor woodworking, bike maintenance, etc) and the sloped floors and drains make it a pain. Nothing like having a nice level floor! Is there any easy way to make one or two of the bays level? Could I just stuff one of the drain pipes and lay some self-leveling cement over one of the bays?

Thanks for any help.

Yes you could do that

probably need to sand the epoxy to create a tooth for it to bond to

maybe use a purpose designed primer as well

I would either do all 3 bays or do nothing.

Agree with above with some addition. If you want to level this with a a self leveler and have it really last, then here are our general recommendations.

1. Lightly grind or sand the floor. Make sure to block off the drains and fill them with sand.
2. Use an inexpensive epoxy and then broadcast sand onto the floor to full rejection
3. After the epoxy is cured sweep/remove the sand leaving the surface like a giant sheet of sandpaper. This gives the leveler a terrific surface to bond to, otherwise with significant changes in temperature the leveler can debond and crack and come up.
4. Pour a self leveler at least 1/2" depth to level out the floor. If you go too think then there isn't enough material to bond together. Make sure the leveler is a 'coatable' leveler and high performance such as a 'polishable overlay' type since these have much higher psi ratings. Don't use an 'underlayment'.
5. Lightly sand the new surface and install a 3 layer 100% solids epoxy system with primer and topcoat.

Thank you for all of the responses!

my guess is the solution will be less than ideal and will create another problem.
