INTRODUCTION TO

SIKA SARNAFIL SELF-ADHEREDSHEET WATERPROOFING SYSTEM

FOR PLAZA DECKAPPLICATIONS

System Description

The Sika SarnafilSelf-Adhered Sheet Waterproofing Systemis designed to protect structures from the effects of water infiltration leading to structural deterioration and interior water damage. The system is primarily intended forplaza decks, split slabs,parking decks,planters, balconies and terraces, and roofing applications utilizing paversor concrete as overburden.Projects with non-removable overburdens such as, but not limited to, cast-in-place concrete or pavers set in mortar must be compatible with electronic leak detection to be eligible for a Sika Sarnafil Warranty. This means there can be no steel reinforcement in the overburden. Where reinforcement is required, synthetic fibers must be used.

The Self-Adhered System design is intended to provide increased security by having the waterproofing membrane bonded directly to the structural concrete deck. The waterproofing membrane is a composite sheet comprised of a waterproofing membrane and a closed cell foam backing layer coated with a pressure-sensitive adhesive. The foam backing layer allows the membrane to better conform to minor surface irregularities, and acts as a separation between the substrate and waterproofing membrane. The pressure-sensitive adhesive is designed to adhere to properly prepared substrates. The Self-Adhered System is ideally suited for new construction, but may be used in renovation projects provided that the substrate is properly prepared.

System Components

The Self-Adhered System design includes the following:

1.Sarnafil G476 Self-Adhered Waterproofing Membrane
2.Sarnafil Drainage Layer
3.Sarnatherm Extruded Polystyrene Insulation (optional)
4.Filter Fabric (optional).

  1. All new and temporary construction, including equipment and accessories, shall be secured in such a manner, at all times, as to preclude wind blow-off or damage.

F.Liquid materials such as solvents and adhesives shall be stored and used away from open flames, sparks and excessive heat.

G.The Applicator should take necessary precautions when using adhesives or surface conditioner around air in-takes. The smell of the adhesive, primer, or surface conditioner could be a disturbance to the building occupants. It is the Applicator’s responsibility to notify the owner and take the proper precautions.

H.The Applicator shall verify that all drain lines are connected and un-blocked before starting work. Report any blockages or non-connected drains to the owner’s representative and/or design professional in writing.
