deck 1st floor slab joints water tight

CPD 1 2015: Best practice for building waterproof concrete.

A393 reinforcing mesh in the top and bottom of a 200-300m slab should be sufficient. At slab-wall joints two faces of 12mm starter bars are not always sufficient to completely control cracking. As a minimum 16mm bars should be used on the outside face and 12mm bars on the inner face all on 200mm centres.【Get Price】

Ensuring Balcony Durability: Waterproofing details that stand.

The balcony is flood-tested by filling with water. The concrete topping slab is placed with careful screeding to ensure uniform slope. Control joints will be scribed into the fresh concrete to limit cracks in the field of the deck.【Get Price】

Floor Slabs | WBDG - Whole Building Design Guide

A typical base floor slab where the design criteria includes controlling water vapor transmission into the interior space but is not concerned about waterproofing the base floor due to hydrostatic pressure loads can be referred to as an imperfect barrier system. The components of the system include a well compacted yet well draining granular aggregate capillary break system placed directly on.【Get Price】

Elevated Deck Trench Drains - Eric'sons Dura Trench

There are two predominant theories for how to keep an elevated deck waterproofed when a channel drain is used. The first method is to keep the trench drain very shallow so that it stays on top of the waterproofing membrane. The second method is to flash the waterproofing membrane into the side of the trench drain.【Get Price】

Concrete Movement Joints | Pavingexpert

The usual recommendation is for some form of movement joint to be created in a non-reinforced slab at a separation of approximately 30 times the slab thickness. So for a 100mm thick slab there should be some for of joint every 100m × 30 = 3000mm = every 3.0-3.6m and in a 150mm slab 150 × 30 = 4500mm = 4.5-5.4m.【Get Price】

Rules for Designing Contraction Joints | For Construction Pros

Rule #7: For tooled or grooved joints depth of the contraction joint should be 1/4 of the slab thickness. For interior floors specify a 1/8 in. edge radius for the top of the groove or joint.【Get Price】
