1.4.7 Statement from the Manufacturer that the system to be installed shall only be performed by authorized and trained personnel.

1.4.8 Statement from Manufacturer that the binders used in the system has been specifically designed for water play surfacing.

1.4.9 A Certificate of Insurance for general and liability of no less than $5,000,000.00.

1.4.10 Sample of the surface system minimum size being 3″ x 3″.

PART 2 • Materials

2.1 Base Construction: ensure that any and all contaminated material and wood fiber systems are removed and properly disposed of. Construct new base or recycle existing materials as per Ure-Tech Surfaces specifications to provide a stable firm base on which to install safety surface system.

2.2 PlaySoft Superior Coloured SBR shall meet the following gradations granulated rubber: 1 – 3.5 mm. Or 1-4 mm depending on desired surface texture.

2.3 PlaySoft Superior Coloured SBR rubber shall meet ASTM D 412 for tensile strength.

2.4 Polyurethane binders shall be specially formulated for playground surfacing, shall contain no TDI, filler minerals such as plasticizers, catalysts, extenders or heavy metals. Weight of polyurethane shall be no less than 8.5 lbs./gal (1.02 Kg/l).

2.4.1 Primer: Single component moisture cured UTS- 136.01 polyurethane primer.

2.4.2 Binder: An elastic polyurethane pre-polymer with minimal odour, excellent weathering and binding characteristics. The use of UTS- 136.01 Urethane is specific to and required for this project. Supplier must receive written authorization prior to installing the product which verifies use supply of urethane specified for this project. No as equal urethane substitutions are permitted. UTS- 136.01 is supplied by Ure-Tech Surfaces Inc. 1-866-211-0191.

2.5 Standard Binder (UTS 136.01) will amber and change the appearance of the finished rubber, usually more noticeable when mixed with lighter colours. Aliphatic binder (UTS 151.01) is recommended for non-yellowing.

2.6 Typically, MDI binders are aromatic however a higher U.V. resistant aliphatic binder is available at additional cost.

2.7 UTS Binders are purchased for both the base and top rubber from North America Suppliers. Proof of Purchase/Origin of materials upon request.

PART 3 • Playground Surfacing

Weather Conditions

3.1.1 Temperatures: minimum 10° during the day and evening hours throughout installation period for the rubber surfacing to be installed. Note: With cooler temperatures rubber finish will be noticeably more rough than a typical in-season installation.

3.1.2 UTS Binder is moisture cured with the presence of water. Sub-base cannot have any puddling or standing water when applying rubber. Once base rubber is applied, the rubber must be free of wetness from dew and/or frost or rain prior to applying top wear course.

3.1.3 When applying multi-colour rubber patterns, the bonding edges must be dry or foaming will occur. This includes bonding to all perimeter materials such as brick, concrete, wood. etc.

3.1.4 Rubber should be protected at all times against frost during the curing of both base and top wear course to prevent freezing of the uncured binder which can cause premature wear and or failure of the performance of the rubber.

3.1.5 October 30 will be the cut off date for starting new installations, unless temperatures are favourable. All installations after this date are subject to a sign off on our Weather & Temperature document.

3.1.6 If temperatures are below 10° tenting and heating is permissible. Tent must be constructed in such a way to withstand weather conditions of fall and or winter weather.

Base Preparation

3.2 In order to ensure the consistent performance of the safety surfacing, bases must be constructed to ensure a firm, stable and draining foundation for the surface. Any and all contaminated materials or materials that are subject to decomposition or expansion shall be removed and disposed of.

3.3 Ensure drainage of the base material is existing or install drainage system under the safety surfacing system.

3.4 Construct bases as per Ure-Tech Surfaces specifications for various site conditions as listed below. Ure-Tech Surfaces cannot guarantee a safety surface over bases that do not meet the base requirements.

3.4.1 Asphalt, concrete or compacted stone bases. Stone bases shall be minimum 3″ depth wet compacted to a 95% proctor density.

Surface Installation

3.5 After the stone base has been constructed to Ure-Tech Surfaces specifications, graded and compacted to proper slope and elevations, install Terratex SD geotextile filter fabric over base, overlapping all joints by 6″. Provide protection to curbs, sidewalks and play equipment to eliminate polyurethane residue on the same.

3.6 Polyurethane and buffings SBR rubber for base mat must be minimum 50% new buffings from recycled tires mixed with binder produced in North America and clearly labeled with a minimum 8% urethane per by weight of rubber. Rubber shall be thoroughly mixed on site to ensure 100% coverage of all particles and poured in place to required thickness to meet critical height criteria of play equipment. Allow 24 hrs. to cure.

3.7 Prior to installing wearing course, the edging shall be primed with diluted polyurethane binder.

3.8 Surface layer of PlaySoft Superior Coloured SBR rubber shall be thoroughly mixed on site to ensure 100% coverage of all particles and poured in place by means of rakes and screed bars and compacted to required density by use of hand trowels and rollers.

3.9 PlaySoft Superior Coloured SBR rubber shall be peroxide cured.

Cleanup

3.10 Remove any spills or residue that may make contact with structure or surrounding curbs or sidewalks. On completion of work and the 24 hr. cure time, remove all protection provided for the same.

PART 4 • Installer Services

4.1 100% coloured SBR granulars are available to meet budgets. Clear and pigmented binders are available for resurfacing existing areas providing additional protection from ultraviolet light and revitalization of existing sites. These binders can be installed by owners or Ure-Tech trained personnel.
