02.08 Casting of a waterproof belt

A waterproof belt shall be constructed around wet areas that are intended to be sealed such as lavatories, kitchenettes, open balconies and roofs, the function of which shall prevent the passage of water in the fill around the tiling between the “wet” area and the “dry” area.

The belt shall be anchored into the structural concrete of the floor with dowels.

The waterproofing system shall come up over the belt and shall cover it and connect with the existing waterproofing.

The height of the belt under walls shall be 7 cm above the height of the flooring.

The height of the belt at door thresholds shall reach the underside of the flooring.

The waterproofing shall be separated in the area of the door using a brass threshold. The waterproofing shall come up over the threshold and connect with it. A cant strip shall be constructed under the belt.

02.09 Concrete surfaces planned for an epoxy coating

A. General

The works in this section shall be performed in accordance with Section 50 of the HNTR for concrete surfaces and as detailed in this specification.

The surfaces shall be cast following installation of sub base and the placement of polyethylene sheets while paying particular attention to the installation of casting breaks, joints, and concrete curing. Joints in the concrete surfaces shall be placed at distances as detailed in the drawings.

0.3 mm thick, polyethylene sheets shall be deployed prior to casting on the ground.

B. Type of floor

The floor shall be Type 02 – Casting Method 001 –”uniform layer” method.

Site 276 DFAC & Energy Center - Israel 23 September 2014

C. Type of concrete

The layer shall be cast using B-40 concrete with a smooth finish. The concrete shall include additives as recommended by the concrete supplier to prevent cracking, including plastic cracks.

D. Preparation and determination of mix ratios

The mix ratios shall be determined based on preliminary testing at a certified laboratory at the Contractors' expense. Compressive and flexural strength of the concrete shall be determined by laboratory testing as required in Israel Standard 118.

E. Level of precision and maximum allowable tolerances

The average tolerance in the planned level and the average tolerance in flatness shall be compatible with a standard level of precision as defined in Table No. 1 of Subsection 50096 of the HNTR. That shall say, a level of precision of ±10 mm in level and 10 mm in average flatness.

F. Formwork

Forms shall be made from sheet steel that are stable during application, compaction and troweling.

Leveling and the determination of heights of the forms shall be performed using survey instruments such as a level with a millimetric scale staff. Leveling and the determination of heights with the use of a leveling tube or water level will not be allowed.

I. Troweling of the concrete surface

1. Leveling, compacting and preliminary troweling

Upon completion of vibrating, the surface of the concrete shall be leveled and compacted with the use of a suitable metal straightedge. Following completion of the

Site 276 DFAC & Energy Center - Israel 23 September 2014 leveling, the height of the concrete surface shall be checked. All recesses shall be filled with more concrete and vibrated and any surplus concrete shall be removed.

2. Final troweling

The Contractor shall take into consideration that the toweling activity requires time, experience, and it shall be performed using a well-trained crew several hours after completing the casting. After leveling as described above, any other activity shall be deferred until a time when the sheen disappears from the water secreting from the surface of the concrete, but before the concrete hardens to such an extent that the final toweling cannot be performed. Final toweling shall be performed with the use of a rotary toweling machine (“helicopter”) by tradesmen skilled in this work. In narrow areas that are difficult to reach, the troweling shall be performed using a plasterer's trowel by a skilled tradesman.

J. Curing

Curing shall begin immediately after the finishing activity and with suitable care in order to avoid damaging the surface of the troweled concrete.

Curing shall be performed by covering [the concrete] with sheets of geotechnical cloth clad with polyethylene sheets to prevent evaporation from the surface. Geotechnical cloth sheets clad in a thermal adhesion process with polyethylene sheets [shall be] as for example TC sheets fabricated for this purpose. The cloth [when] coming into contact with the concrete surface shall be wetted lightly before the sheet is rolled onto the concrete surface. Minimum curing time shall be 10 days. The use of a vapor barrier material will not be permitted.

K. Joints

Joints shall be formed in accordance with the details as required in the drawings and in conformance with all requirements of Subsection 5004 of the HNTR.

Prior to cutting the joints, the Contractor shall mark the alignment with paint with a straight line perpendicular to the troweling. Cutting shall be performed with the use of a concrete cutting machine with a diamond blade that includes a control device that allows cutting in a straight line.

The cutting of dummy joints shall be performed as soon as possible the day after casting but in any case with high precision so that the edges of the joint will not crumble or become damaged.

The cutting of casting break joints shall be performed at a time as close as possible to their filling with filler.

The joints shall be filled in for their entire length with fire-resistant and oil-resistant

Site 276 DFAC & Energy Center - Israel 23 September 2014 elastomeric material.

The filler shall be applied so that the top face of the filler will be flush with the top surface of the slab while taking care not to spill the material beyond the sides of the joint. Leaks and stains shall be cleaned immediately on the day of application using materials recommended by the supplier.
