Fundation

Fundation

Fundation

(OP)
My contractor just poured foundation last week.
He is already framing, is this normal to do this so quick, also the foundation is not smooth, some places you could see
Small rocks exposed 6" wide by 6'feet long.
Should I be worried?

RE: Fundation

In the UK with our cements we get about 2/3 of the 28 day (or full) concrete design strength after 7 days so I would consider it ok to start erecting the framing. It would be unusual to get anything like the full load on an ordinary building structure untill well after 28 days from pouring foundation concrete.
What do you mean by "small rocks exposed"? Do you mean the agregate in the concrete? If it is a steel frame building and grout is poured under the baseplates after lining & leveling then dont worry about the roughness - the grout will fill that out.

RE: Fundation

In the US colonies it is typical to start that quick.  Heavy loading should be avoided, ie anchor bolts should not be tightened for A few more weeks.  

The gravel is usually tamped down when the mix is in the plastic state.  The exposure of the rocks, sould be several things.  I would quess it indicates a cold bond joint.  This is when the concrete truck batches were not consective and the first placed concrete was hardened before the next truck arrived.  Depending on the floor covering it should be filled and leveled with grout.  Watch for cracking too.

White Paper - Addressing Tooling and Casting Requirements at the Design Stage
Several of the tooling and casting requirements of a part can be addressed at the design stage. If these requirements are not addressed at the design stage, lot of time is spent in design iteration when the design reaches the die caster. These design issues lead to increase in time and cost of production leading to delay in time to market and reduced profits for the organization. Download Now
White Paper - The Other Side of Design for Assembly
Assembly level constraints need to be satisfied before the design can move downstream. This white paper will go through the various assembly level issues, which need to be tackled by various organizations on a regular basis. Know more about DFMPro, a design for assembly software. Download Now
