What problem did the basement have?
The basement had a deteriorated concrete floor and a drain system that needed attention. Rockzen USA says basement floor problems in NYC are rarely just about the floor, and that cracked concrete, standing water and slow drains can point to deeper problems. No outside source was reviewed for those points on this page. The size of the floor, the earlier water conditions and the drain fault are not published. Rockzen USA handles basement waterproofing and floor work across Manhattan.
What did Rockzen USA do?
The work ran in six stages. A free site visit came first. The new floor came last.
Free site visit
The team assessed the basement floor condition and the existing drain system.
Old concrete removal
The crew broke out the deteriorated concrete floor and removed it.

Broken concrete and soil piled up as the old floor came out.
Drain line inspection
The crew inspected the drainage system and identified the areas that needed attention.
Drain line repair
The crew completed the required drain line work before any new concrete went in.

Drain piping exposed below the floor, with newer fittings joined to older pipe.
New concrete floor
The crew poured, finished and leveled the new basement concrete floor.
Final result
The basement now has a clean, functional floor with the drain work completed.

The project covered the old concrete floor, the drain line and a new poured and leveled concrete floor. Floor size, concrete thickness and strength, drain line type and length, the drain fault, waterproofing products and permit status are not published.
