§ 35. Waiver of arbitration; arbitrators' award conclusive. The filing of a notice of lien shall not be a waiver of any right of arbitration of a contractor, subcontractor, material man or laborer secured to him by his contract to furnish labor or materials. In case the arbitrators, in any arbitration proceeding had pursuant to any such contract, shall determine the value or price of labor performed or material furnished, their award shall be conclusive as between all parties to the arbitration in any action to foreclose the lien.
