FAQ:

What sizes of crushed glass should I choose for different applications?

For mulch, 5–12 mm tumbled chips balance sparkle and safety. For resin-bound pavements, 2–4 mm angular chips give grip and a smooth finish. For concrete/terrazzo exposure, combine 0–4 mm fines with 6–12 mm decorative chips for depth.

Is crushed glass safe for barefoot areas and playgrounds?

Yes—select tumbled crushed glass with rounded edges and verify the surfacing system’s slip/impact ratings. Avoid sharp, freshly angular chips where skin contact is likely unless encapsulated in resin.

Can crushed glass replace sand in concrete mixes?

Partially, yes. Start with 10–20% fine aggregate replacement by mass, pair with SCMs (e.g., Class F fly ash, slag) to mitigate ASR, and run trial batches to confirm strength and expansion limits.

Is there a risk of glass popping or cracking in fire features?

Use only certified, tempered fire-glass media. Standard decorative crushed glass not rated for high heat may fracture.

How does crushed glass compare on lifecycle cost to bark mulch or gravel?

Initial cost can be higher than bark, but crushed glass does not decompose, stain, or compact as quickly—reducing refresh frequency. Against premium decorative gravel, costs are comparable while offering broader color control.

Can I mix colors to create gradients or logos?

Yes. For resin-bound or terrazzo, pre-weigh color fractions for repeatability. In loose-lay mulch, install in bands with edge restraints to maintain clean transitions.
